VApplication -led March 17, 1920.l Serial No. 366,605.

. pumps in which water or other liquid will be raised by employing the momentum of a fluid such` as compressed air( the supply of which is controlled by suitable valve devices.

l prefer to use my improved pump in deep wells, and Yfor raising water containingsand and gravel, but it has other applications. rl`he desirability of my construction is due to the absence of parts likely to get out of order, and to the simplicity of its mecha-A nism. 1 l

ln the drawing herewith anelevation, partly in -vertical section is shown of construction einbodying my invention. l do Ynot show any valve device used to control admission and exhaust ofv the impelling fluid, such as compressed air, as there are well known vforms of 4-way valves which are usable.

The drawings are diagrammatic, as in practice the proportions, designs, and respective positions of various parts may differ from those illustrated.

l provide as compressed airinlet means, a pair of pipes 3, 4 each having a branch 3, 4TL to act as an exhaust pipe. VThese four pipes are controlled by a 4-way rotary or other suitable valve, not shown but lmown as aforesaid, which will be operated by any convenient means so asto at one time open pipes 3 and 4, and close pipes 3a and 4. Alternately the valve will close pipes 3 and 4a and open pipes 3a and 4. Y

In pipe 3 is a float ball 1 and in pipe 4 a float ball 2. These balls have respective seats 12, 122L above them, and respective gratings 13, 13a below them.

The gratings 13, 13a prevent the balls dropping into the pump barrels next mentioned and when any ball is raised to its seat it prevents outward passage of water past it.

I provide two pump barrels, 5, 6 and connect to them the pipes 3, 4 respectively at suitable distances below the heads of the barrels. The'latter are united at their. heads and at their bases. f

Attheir upper ends they are joined to the baseof a water receiving chamber 11, which will receive water from each barrel 5, 6, alternately when the pump is at work.y

Chamber 11 contains a rocking lever 18 which at each end carries a connection or rod 18a, 18h, respectively, each carrying a float valve V19, 20, respectively. `The lever.

18 is caused to alternately raiseand lower its valves, thusfclosing and opening the seats 19a, 20a through which rods 18, 181 extend,

and which are provided to allow passage of water from barrels 5 and 6 into chamberll whichhas any suitable delivery, as pipe. 21. The barrels 5, 6 are at .their bases united by tubing 7 of U form. The limbs of the U tubing, or the bases of barrels 5, 6l are provided with valve seats 8, 9. The U tubing .i

contains a* ball valve 10, which when the pump is operating will be moved by water 'up vone or other limb of the U tubing, water being then forced down barrel 5 or 6 as the case may be. This ball valve will thus close Each branch pipe 14, 15 extends down-V ward for any suitable distance to enter the water to be raised and istted at -or above its base with afseat, a grating and a ballor automatically to close its seatexcept when raised as explained hereinafter. The respective seats are marked 16, 17, the gratings 16a, 17a, and the ball or foot valves 1613171. Y n

To operate this pump its lower part is immersed in water, which may, but need not, reach to level A. For starting purposes the barrels 5 and 6 are then supplied with water (through delivery pipe 21 for example) so as to fill the said barrels and the connected pipes 3 and 4 to a suitable height--as to seats 12, 12a of float valves 1, 2.

The aforesaid rotary or other control valve device (not shown) is then operated, and the air under pressure is admitted, through for example pipe Y3, the outlet 4a being kept at this time open. The said compressed air flows forward and presses the foot valve each `ball or foot valve falling Water in pipe 3 into barrel 5, some of the water 'in Awhich is accordingly forced up ward, and other water therein is forced downward. The water 'forced upward closes valve 19 on its seat and moves the rod 18a and the lever 18 and'accordingly`moves rod 18b and opens valve 20. p

rlhe water forced as stated down barrel 5 forces ball l0 before it so` that that ball rises to'and closes seat 9 in barrel 6; but rduring the rsaid ball movement it forces water in barrel 6 to move upward.

Since valve 9 has been suddenly closed by ball 10, asuction is caused at and about 9- by theV water flowing up. barrel -thus water is drawn into 6 through pipe l5, past valve 17h which is lifted by the suction. The water thus raised in barrel 6 passes the seatfQOa and enters'the chamber ll until Vthe conclusion oftheimp'etus of water up barrel 6 whereupon valve 17h closes on seatl and suction up pipe 15 ceases. Then water isthus pumped up barrel 6 -t-he 'water ills pipe 4 up yto the loatvalve seat 12a. During the actions just explainedany -air inspipe 4 becomes discharged through-the pipe-4.

The next action of the said rotary or other valve device closesthe pipes V 3, 4*?, and opens the alternate set of `pipes 3L and 4, and ladmits 'air under pressure into pipe 4, while the compressedv air in-pipe 3 becomes discharged through pipe 3a.

vThe vair thus admitted -to pipe V4 forces the water in that pipe into barrel 6, land (in Athermanne'r described as to'barrel 5) Athus closes valve 20, and opens valve 19. The

vpressure 'of water downward in barrel 6 water is 'drawn through pipe-14, lifting ball ll/Vater valve 16h, iand entering barrel 5.

fromA barrel 5 yis thus delivered into `chamber 11 yas will be` obvious. l

W hen water is pumped up barrel 5 as last 'explained the water iills pipe'S to the iioat valve seat l2.

@ne series of pumping movements is thus completed and the pump further operates repeating the series, the pipes 3, 4a being again opened, and pipes 3a, 4 being closed.

Having described this invention, what is claimed is:

l. In a pumping apparatus, the combina- -tion of a water chamber having an' outlet, a pair of barrels each communicating` at one end with said chamber, said barrels being in communication with `each other at their opposite ends, each of said barrels having an inlet, means for supplying fluid under pressure -to said barrels, valves for controlling the communication between the barrels and said chamber, valves for controlling the inet to said barrels, anda valve `for controllingv the communication between lthe barrels,

all of said rvalves beingl adapted vfor operationalternately in opposite directions.

g apparatus, the combination of -a receiving chamber having an outlet, a pairV of barrelsV each provided with a valve-controlled opening at one end in communication with said chamber, a rocking lever in'said chamber and provided with valves -for controlling said openings, each o-said barrels being provided at its opposite end with a valve seat, a tube connecting said valve seats, a valve in said tube adapted to 2. ln a pumpinT Aalternately close said seats, apair of valvecontrolledliquid supply pipes in communication with said barrels, and a pair oi valvecontrolled supply pipes for iiuid underpressure also in communication with said barlrels, each of said tubes having an exhaust opening, all of said valves being adapted for valternate operation to supply iiuid under pressure and liquid to -one oi' said barrels.

In witness whereof I have hereunto set my hand.
